Connect the Stage Cable to the Lemo Connector on the stage and connect the other end to the Stage Connection Socket (1).

  • Page 11: Sample Preparation

    Loading a Sample The Microscope Slide Holder is fitted on to the LTS420 and the holder is not touching the silver heating/cooling block, it should hover just above Note: if necessary the Microscope Slide Holder can be bent with a little force into shape to help it to hold the microscope glass slide.

  • Page 12: Using The Heat Shield

    Using the Heat Shield If the temperature controlled experiment requires extra temperature stability, use the supplied Heat Shield to cover the heater. Use the Y-manipulator (1) to move the Micro- scope Slide Holder to the middle of the heating bock and use the X-manipulator (2) to move the Microscope slide holder to the home position (8mm from the edge).

  • Page 13: Cooling Connections

    Cooling Connections These connections need only be made if the experiments are to be carried out below room temperature using the LNP95 system. The Dewar siphon (1) is the thick white foam tubing and is attached to the liquid nitrogen Dew- ar.

  • Page 14: Purging Procedure

    Purging Procedure Before starting a cooling experiment, you will need to purge air from the stage chamber with dry nitrogen. This will remove the water in the air which would otherwise condense and freeze on the sample disrupting your image quality. Before you can start purging, the LNP95 must be set to manual mode.

  • Page 15: Purging The Stage Method 1

    Purging the Stage Method 1 There are two methods for purging the stage. Method 1 uses recycled nitrogen gas produced by the LNP95 from the 2L Dewar. Make sure the stage lid is in place and the stage door is closed. Switch on the temperature programmer and set the limit to 40°C.

  • Page 16: Purging The Stage Method 2

    Purging the Stage Method 2 This method uses an inert gas from a gas cylinder to purge the stage at temperatures above ambient when the LNP95 is not required. 1. Make sure the Stage Lid is in place and the Stage Door is closed.

    Appendix Window Assembly Lid Window Assembly To replace the windows in the Stage Lid (1) use the Window Tool (2) and align the two wide spacing pins to the Tube Clip Holder holes and unscrew the Lid Insert (3). The Stage Lid and Lid Insert should be turned upside down as shown in the diagram opposite and reassembled in the order indicated.

  • Page 18: Replacing The Microscope Slide Holder

    Use a flat screw diver and remove the screw (1). Take out the Microscope Slide holder from the XY Manipulator Assemble(2) Do the reverse to replace the LTS420 with a new Microscope Slide Holder. Make sure the 2 holes on the holder are lined up with the two notches (2) on the XY Manipulator Assembly.

  • Page 19: Ltse420 With Internal Electrical Contacts

    LTSE420 with Internal Electri- cal Contacts Option Only read the following if the stage is supplied with internal electrical contacts for the LTSE420 or Liquid Crystal Pro Stage. The stage is supplied with two internal electrical contact connectors (1) wired to an external Lemo connector (2).

  • Page 20: Using The Internal Electrical Contacts

    Using the Internal Electrical Contact The internal electrical contact has a self-closing spring loaded pin (1). Using a finger tip push in the pin to open the electrical contact and insert a wire into the contact (2). Release the finger when the wire is in place.

  • Page 21: Lemo Connector

    Lemo Connector Remove the Lemo plug by holding it firmly and pull it gently away from the Stage. Wire up the Lemo to your instrument. To reconnect the Lemo, line up the red dot on the Lemo plug (1) to the red dot on the Lemo socket (2) and push the Lemo firmly into place.

  • Page 22: Liquid Crystal Stage Pro

    Liquid Crystal Stage Pro Only read the following if your stage is a LTSE420 Liquid Crystal Pro Stage. The Liquid Crystal System Pro is supplied with a Liquid Crystal Slide Holder (1) and 5x Liquid Crystal Cells (5um gap, capillary fill, ITO coated and anti parallel aligned).

  • Page 23: Spares And Accessories

    These spares are organised into convenient kits. Purchase a spares kit to avoid downtime with your stage and eliminate future shipping costs. The LTS420 heating element is extremely durable if used carefully. However it can be easily scratched, which will compromise the heat flow to the sample and reduce accuracy. The platinum temperature sen- sor is brittle and can be broken if cleaning is not carefully performed.

  • Page 25: Troubleshooting

    Troubleshooting Cooling fault diagnosis Ensure that all connections to the stage and Dewar are as described in the specific manual and that the stage lid and top windows are properly sealed. 1. The cooling rate is less than programmed. There can be several causes of this problem, the most likely being that one of the connectors has become blocked or damaged.
